Unmarried parents in the AHEAD study derive the majority of their long-term care hours from their children, and child caregivers are generally unpaid. This paper examines the extent to which the division of end-of-life transfers compensates caregiving children. In a model of siblings' altruistic contribution of care to a shared parent, the parent's estate division is found to influence total family care, even where care contingencies are unenforced. Evidence in the AHEAD data that end-of-life transfers favor both current and expected caregivers, and that children make altruistic but resource-constrained caregiving decisions, is consistent with a theory of estate division in which planned end-of-life transfers elicit care from altruistic children.
